Now it’s the self-described schizophrenic who went scot-free just 24 hours after throwing a brick at his Washington Heights neighbor, then lunging at her with a knife.

Police reportedly told the victim that no charges would stick because of his mental health. Instead, they took him to a hospital for a psych evaluation; he was released the next day and told to undergo “substance use treatment” at a rehab facility.

Worse: When the victim initially called the 33rd Precinct to ask for a copy of the police report on the incident, she was told that none had been filed. On Monday, after The Post reported her story, the precinct asked her to come back to give a statement.

So her fury at how cops have handled the case thus far certainly is understandable. But it’s not necessarily the whole story.

New York has seen other tragedies involving emotionally disturbed persons, some involving people who were shot down by police.

And, as we’ve noted, a large part of the problem is the de Blasio administration’s continuing refusal to take the challenge of violent EDPs seriously. So you can sort of see why cops might believe that any effort they make toward bringing criminal charges would be for naught — though it’s no excuse for police not doing their jobs.

We’ve seen no sign here of the Ferguson Effect — cops refusing to proactively fight crime for fear department brass won’t back them up — that has contributed to ongoing violence in Chicago and elsewhere. Yet the host of politicians looking to further handcuff the NYPD means you can’t rule it out.

Commissioner James O’Neill needs to get on top of this pronto and ensure that these cases are merely flukes that fell through the cracks, not a sign warning of a terrible trend.
